Deadline for abstract submission extended to December 20, 2015The 21st Workshop on Structure and Constituency in Languages of the Americas (WSCLA 2016) will take place at the Université du Québec à Montréal (UQAM), Montréal, Canada, April 1-3, 2016.The Workshop on Structure and Constituency in Languages of the Americas (WSCLA) is an annual linguistics conference, which started in 1995. The central objective of WSCLA is to bring together linguists who are engaged in research on the formal study of the Aboriginal languages of the Americas in order to exchange ideas across theories, language families, generations of scholars, and across the academic and non-academic communities who are involved in language maintenance and revitalization.Abstracts are invited for papers in any area of formal linguistics (including phonetics, phonology, morphology, syntax, semantics, and pragmatics) within any theoretical framework. We welcome papers that address diachronic, sociolinguistic, or applied topics from a formal perspective, and we are especially interested in papers seeking to correlate the interests of formal linguists and the concerns of indigenous communities.The organizing committee for WSCLA 21 would also like to announce that this year’s meeting will include a special thematic session on Polysynthesis and Wordhood in Languages of the Americas. Abstracts which address this theme are particularly solicited, although abstracts on other topics are of course welcomed.We are pleased to announce the following confirmed invited speakers:Ryan Bennett (Yale)Brandon Fry (Ottawa, student guest speaker)Sarah E. Murray (Cornell)Kahtehrón:ni Stacey (Kanien'kehá:ka Onkwawén:na Raotitióhkhwa Language and Cultural Center)Martina Wiltschko (UBC) We expect a volume of conference proceedings to appear in the UBCWPL series.Abstracts should be submitted to the EasyChair website at this link:https://easychair.org/conferences/?conf=wscla2016Abstract submission guidelines :- Please submit your abstract for a paper in .pdf format following the requirements listed below, before midnight EST on Dec. 20, 2015.- Abstracts should be anonymous.
